Hi everyone,

I was looking to see if anyone would know if there is a link or an online PDF chart that would reflect the California Building
Code requirements for drilling joist and trusses. I just got popped for having my holes to close together. I am told they have to be four
inches apart. That is new to me. I have been an Electrician since 1992 and have never heard that before. So... does anyone have some
input, I would really appreciate it. In my defense I have been a commercial electrician for the last decade. This was the first home in
long time. Things change.
Thanks,
Klbrnt

The drilling and notching is according to the reqular building codes. If you are reffering to manufacured lumber you need to follow the specs from the maufacture.
What did you do?
Will the framing need to be repaired?

Chris why are you sending the poor sole to another forum. This should be the place.

Indeed. The UBC is extinct, try IRC R502.8.1 for drilling and notching sawn or dimensional lumber. Engineered lumber defaults to the manufacturer specs as mentioned earlier. Be aware that holes too close together for joists near plate line supports in cantilevers is a tear line to be avoided. Maybe that is what might be tagged. A repair doubler can be an answer.
